Η Microsoft κυκλοφόρησε χθες το Patch Tuesday Ιουλίου 2022, το οποίο διορθώνει 84 ευπάθειες ασφαλείας. Μια από αυτές, είναι μια zero-day ευπάθεια που είχε ήδη χρησιμοποιηθεί σε επιθέσεις.
Τέσσερα από τα 84 σφάλματα που επιδιορθώθηκαν, ταξινομούνται ως “Κρίσιμα“, καθώς επιτρέπουν την εκτέλεση κώδικα απομακρυσμένα. Τα υπόλοιπα 80 θεωρούνται σοβαρά.
Στην παρακάτω λίστα μπορείτε να δείτε τις κατηγορίες στις οποίες ανήκουν οι ευπάθειες που διορθώνονται με το Microsoft Patch Tuesday Ιουλίου:
- 52 ευπάθειες που επιτρέπουν την απόκτηση περισσότερων προνομίων
- 12 ευπάθειες που επιτρέπουν την εκτέλεση κώδικα απομακρυσμένα
- 11 ευπάθειες που επιτρέπουν αποκάλυψη πληροφοριών
- 5 ευπάθειες Denial of Service
- 4 ευπάθειες που επιτρέπουν την παράκαμψη λειτουργιών ασφαλείας
Σε αυτή τη λίστα δεν περιλαμβάνονται δύο ευπάθειες που είχαν διορθωθεί προηγουμένως στον Microsoft Edge.
Microsoft Patch Tuesday Ιουλίου: Διορθώνει zero-day που χρησιμοποιήθηκε σε επιθέσεις
Η zero-day ευπάθεια που διορθώθηκε αυτό το μήνα, είναι μια ευπάθεια που επιτρέπει την απόκτηση περισσότερων προνομίων στα ευάλωτα συστήματα.
Η Microsoft ταξινομεί μια ευπάθεια ως zero-day εάν αποκαλύπτεται δημόσια ή γίνεται ενεργή εκμετάλλευση χωρίς να έχει κυκλοφορήσει επίσημη ενημέρωση κώδικα.
Η ευπάθεια zero-day που χρησιμοποιήθηκε σε επιθέσεις και διορθώθηκε τώρα, παρακολουθείται ως “CVE-2022-22047 – Windows CSRSS Elevation of Privilege Vulnerity“.
“Ένας εισβολέας που εκμεταλλεύεται επιτυχώς αυτήν την ευπάθεια, μπορεί να αποκτήσει SYSTEM privileges“, εξηγεί η Microsoft.
“Με αυτό το επίπεδο πρόσβασης, οι επιτιθέμενοι μπορούν να απενεργοποιήσουν local services, όπως Endpoint Detection και Security εργαλεία“, δήλωσε στο The Hacker News ο Kev Breen, διευθυντής έρευνας για απειλές στον κυβερνοχώρο στην Immersive Labs. “Με SYSTEM access μπορούν επίσης να αναπτύξουν εργαλεία όπως το Mimikatz που μπορούν να χρησιμοποιηθούν για την ανάκτηση ακόμη περισσότερων λογαριασμών σε επίπεδο διαχειριστή και domain, διαδίδοντας γρήγορα την απειλή“.
Αυτή η ευπάθεια ανακαλύφθηκε εσωτερικά από το Microsoft Threat Intelligence Center (MSTIC) και το Microsoft Security Response Center (MSRC).
